Specification of Letters Patent. Patented J 11119 18, 1918 Applicationfiled August 20, 1917. Serial No. 187,248.

To all whom it may concern:

Be it known that I, HENRY E. Pnrnnsolv, a citizen of the United States,and resident of Seattle, county of King, and State of Washington, whosepost ofiice address is 2922 3rd avenue west, have invented a new anduseful Improvement in Box-Fresses, of which the following is aspecification.

This invention relates to improvements 1 n box presses of the typeemployed for pos1- tioning and holding the tops on fruit boxes whilethey are being nailed and the ob ect of this improvement is to provide astrong and simple press of this nature that will exert a pressurethroughout the entire length of the boards that form the top of the boxwhile the top is, being fastened on.

A further object is to provide yielding means for holding the end cleatsand the cover boards of the box in their proper position in the pressframe preparatory to placing them on the box. a

Still further objects are to provide yieldin pivots for the press frameand to provide suitable mechanism on the lower part ofthe frame forlocking the press frame down on the top of a fruit box. a

The inventionconsists in the novel constructure adaptation andcombination of parts of a box press as will be more clearly hereinafterdescribed and claimed. In the accompanying drawings Figure 1 is a viewin perspective of a box press embodying this invention as it may appearwhen in use.

Fig. 2 is a view substantially in vertical mid section of the same in aninoperative position. r

Fig. 3 is a view in perspective illustrating the press frame.

Fig. 4 is a fragmentary sectional view illustratin one ofthe springs forholding the end 0 cats and cover boards for the boxes. I r

In the boxing of fruit and particularly apples it is customary to formthe cover of two separate boards and to fill the boxes slightly abovethe level of the top and then to secure the covers tightly over thefruit.

The boards used for the cover are usually of thin material and are oftenbowed upwardly in the center by the pressure of the fruit, so thatcleats must be placed across the ends of such boards and the nailsdriven through both the cleats and boards to hold The press framehereinafter described is provided with devices for engaging and holdingthe cover boards and cleats, and with two spring members that extendlengthwise centrally of the two boards that form the box cover andyieldingly hold such boards to prevent them from being broken by thefruit heaped above the center of the box when the ends of the coverboards are drawn down onto the top of the box for nailing.

Referring to the drawings throughout which like reference numeralsindicate like parts, the numeral 5 indicates a rectangular frame mountedon legs 6 and having an upright box-like structure 7 secured to the rearside thereof.

The box-like structure 7 is formed with a rearwardly inclined portion 8on its front side against which the press frame rests when not in useand has a receptacle on the top thereof that is divided into a largercentral compartment 10 for cover boards and. two smaller endcompartments 11 for end cleats.

The front portion of the rectangular frame 5 is provided with oppositelydisposed L-shaped guides 12 for the reception of boxes 13 upon whichcovers are to be placed.

14 is a stop against which the bottom of the box abuts when it is placedon the guides 12 and pushed back into the correct position for having acover placed thereon.

The press frame comprises two transverse members 15 to which arefastened two longitudinally extending spring members 16 having angularlybent ends 17 to which are secured end cross bars 18.

'The members 15 are pivoted as at 20 to two springs 21 that extendthrough slots 22 in the wall 8 and are rigidly secured to a fixedsupport 23.

The ends of the cross bars 18 are turned inwardly as at 24 to form stopsagainst which endcleats 25 may rest when the press frame is in anupright position.

26 are springs that co-act with studs 27 in holding the end cleats 25and also co-act with studs 28 and 28' in holding the cover boards 30 forthe box.

When the press frame is in the raised position as shown in Fig. 2 thecleats 25 may be inserted between the springs 26 and studs 27 and thecover boards may then be laced on the cleats, the edges of the coveroards resting against the studs 28, and28', respectively, which serve asstops and positioning means and the ends i015fthescover boards:beeV

ing engaged and held by the springs 26.

The end bars 18 of the press frame' areeach pivotally connected at amedial point with I rode 31""that extend downwardly'bn opposite sides ofthe frame 53nd are articn lated with opposite ends, respectively, of aenossa ar w hat ise ecmi d' ai-IfQ-Qt {lever imr isins v o iv re'entimmbersw zathat are pivotally connected with the rear legs; 6.The-forward. endso the -membe s 1 8 areseen-red .together and; providedWith-ta. foot;
